TOOL-HOLDlNG DEVICE.

SPECIFICATION forming part of Letters Patent N 0. 729,319, dated May 26,1903. Application filed December 27,1902. Serial No. 136,796. (Nomodel.)

."0 all whom, it may concern:

Be it known that I, WALTER BAKER Fow- LER, a citizen of the UnitedStates, residing at Lawrence, in the county of Essex and State ofMassachusetts, have invented certain new and usefullmprovements inTool-HoldingDevices; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilledin the art to which it appertains to make and use the same.

My invention is an improved tool-holding device especially adapted forholding chisels, plane-bits, and other tools at the required angle withreference to a grindstone or other device when grinding or sharpeningthe tool to cause the same to be beveledto a cutting edge at one end andat a desired angle; andit consists in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

The object of my invention is to provide a novel device of thischaracter which is extremely cheap and simple, is very strong anddurable, is thoroughly efficient in holding a tool while grinding orsharpening the, same, and which is adapted to hold the tool at anydesired angle.

In the accompanying drawings, Figure 1 is a perspective view of atool-holding device embodying my improvements. Fig. 2 is a sideelevation of the same, showing the reverse side thereof. Fig. 3 is anend elevation of the same.

In the embodiment of my invention here shown I provide a frame 1, whichis preferably a single casting comprising a table 2, having a planeupper side, a vertically-disposed side flange 3 at one side of the tableand projecting from the surface thereof, brackets 4, which depend fromsaid table near the sides thereof and nearer one end thereof than theother,and a web 5 under the table unitedthereto and united to andconnecting the brackets 4 together, the said web having a central hubportion 6, which is provided with a screwthreaded bore adapted to beengaged by a clamping-screw, which may be employed to clamp a plane-bitor similar implement on the table when the plane-bit is provided with alongitudinal slot through which the said screw may extend. A roller 7 isdisposed between the lower ends of the brackets 4 and is journaled on anaxle 8, which connects the lower ends of the brackets together. I alsoprovide a clamping-yoke 8, which is adapted to'be disposed transverselywith reference to the table and has shoulders 9 on the inner sides ofits depending arms 10, at the lower ends thereof, to engage the underside of the table at opposite sides thereof, and the said yoke isprovided with a clamping-screw 11, which is adapted to bear on the upperside of a plane-bit, chisel, or other tool or thing to be ground orsharpened, as shown in Fig. 1 and also in Fig. 3 of the drawings. Thesaid yoke, as willbe understood, is shiftable 1ongitudinally withreference to the table, and the function of the flange or rib 3 is tobear against one side of the bit or tool to dispose the same parallelwith the table, so that its cutting edge when ground will beperpendicular to its side edges.

By reason of the brackets 4, which carry the roller, being out of thecenter of the table the tool or bit clamped on the table may be disposedat any appropriate angle with reference to the grindstone or oil-stoneby projecting one end of the tool or bit from the appropriate end of thetable.

From the foregoing description, taken in connection with theaccompanying drawings,

the construction and operation of the invention will be'readilyunderstood without requiring a more extended explanation.

Variouschanges in the form, proportion,

and the minor details of construction may be resorted to withoutdeparting from the principle or sacrificing any of the advantages of.thisinvention.

Having thus fully described my invention,

what I'claim as new, and desire to secure by Letters Patent, is I 1. Atool-holding device of the class described, comprising a table having asupporting-roller on its under side, whereby it may be inclined, and ayoke detachable from and longitudinally shiftable on said table, saidyoke having means to clamp a tool or bit on said table, substantially asdescribed.

2. A tool-holding device of the character described, comprising a tableand side flange extending from its upper side, bracket-s depending fromits lower side, a supportingroller carried by said brackets, and meansto secure a tool or hit on said table, substantially as described.

3. In a tool-holding device of the character described, the combinationof a table having a supporting-roller on its under side and a yokelongitudinally shiftable on and detachable from the table, said yokehaving means to engage the sides of the table and being provided withmeans to clamp a tool or hit ro thereon, substantially as described.

In testimony whereof I have hereunto set my hand in presence of twosubscribing wit- WALTER BAKER FOWLER. Witnesses:

HARRY R. Dow, ANNA T. MULHOLLAND.
